Hi, I am brand new to java but I have a requirement where i am suppose to use Groovy.
So is there any good features that can address my requirement? I have string like str = "This is a sample text. Trying to explore groovy. In India, Bangalore, Harsha, N., with experts help"; In the above string am only interested in the Name of the person "Harsha" which will always be followed by letter N. and "," (N stands for Name which will be after every name) another example is , str = "This is a sample text. Trying to explore groovy. In India, Bangalore, Daniel O' Relly, N., with experts help"; Here I need to extract " Daniel O' Relly" which is followed by N. and "," to continue So is there any features available in groovy that will do the job?? |
Sounds like you want a regular expression.

Here is a good source of code snippets. See the String section and search for "=~" for the regex stuff

mystring =~ /\bJ[a-zA-Z]+/ will return a list of all words that start with a capital J.

Groovy 1.6.3 adds String.find to the regular expression toolkit and it's built for this kind of thing:
str = """Background: Educator who unsuccessfully tried to obtain a teaching
position sued county board of education in state court to recover \$100,000 in compensatory damages for alleged age discrimination under the federal Age Discrimination in Employment Act (ADEA). Board filed a motion to dismiss.
The Circuit Court, Baltimore County, Jakubowski, J., granted the motion and dismissed educator's claim without prejudice. Educator appealed.""" str.find(/\b\S+ J\./)

So is the Regular expression feature in groovy provide more feature than the regular expression of Java??

Is it fair to assume this is an assignment on a programming course?

Hi,
calling a method which I pass as a String parameter works - eg def foo() { println 'bar' } def l = 'foo' "$l"() But how do I instanciate a class with the same mechanism - eg class Foo { def bar() { println 'foobar' } } def l = 'Foo' new "$l"().bar() breaks with org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, test.groovy: 8: unexpected token: @ line 8, column 5 new "$l"().bar() how can I create instances with that mechanism ?

I think you need to use Java reflection:
Class.forName("my.package.Foo").getConstructor(...).newInstance(...) It's a shame that you have to use a completely different syntax, but in some common cases, the parser needs to know whether a given name starts with a capital letter during parsing, to know whether its a type or a method, e.g.: String x // declares variable println x // calls println method "$blah" x // What does this do?

Harsha1 wrote: > > So is the Regular expression feature in groovy provide more feature than the > regular expression of Java?? Well, it uses the Java regular expression underneath. So in terms of what strings it can match, and what information you can get, its the same. It just provides a more convenient syntax for it.
